Application filed January 13, 1910. Serial No. 537,830.

To all whom it may concern:

Be it known that I, EDUARD MERT'ENs, a subject of the Emperor of Germany, residing at Freiburg, Baden,-Germany, have invented a new and useful Apparatus for Var. nishing Roller-Shaped Bodies, of which the following is a specification. 4

This invention has reference to apparatus for varnishing roller shaped bodies by" means of a fine jet of liquid varnish applied A method of coating the surface of a roller with varnish or the like is known in which the roller is caused to rotate continuously in a fixed bearing upon a turning lathe or the like and a flask containing the varnish is placed upon the traveling saddle of the lathe, from the fine nozzle of which flask the liquid flows on to the surface of the roller. In this method of varnishing when there is any. irregularity in the motion of the roller the nozzle is not always atthe same distance from the surface of the-roller or does not always lie regularly thereon, and this results in uneven application of the varnish.

In accordance with my invention the nozzle of the varnish squirt is allowed to swing under a predetermined pressure only in one plane-as nearly as possible in a vertical plane when the roller is mounted in horizontal bearingsso that it always makes regular contact with the surface of the roller in spite of unsteady running or pitching .of

the turning lathe and a nozzle E which is connected by means of a flexible or other tube D with the flask Ais mounted in a block G' which is attached by means of a hinge F to the standard B so that the nozzle E can swing in .a vertical direction HH, when the roller J pitches/or rocks in its The axis of the hinge F is for this purpose mounted parallel to the axis of the roller J. The weight ofthe bearing block. G

presses the nozzle E firmly upon the surface of the roller J and the said nozzle is thus caused to partake of all the up and down movements of the surface of the roller, without displacement of the nozzle in the direcbearings, but cannot move at all sidewise.

tion of the axis of the roller being possible.

Instead of the saddle or support being slidable, the roller itself may be arranged to slide in the direction of its axis.

What I claim asmy invention and desire I to secure by Letters Patent is:

' Apparatus for varnishing roller-shaped bodies by means of' a fine jet of liquid varnish-applied spirally to the body, comprising in combination with a turning lathe adapted to rotate the'body on its longitudi nal axis and having a traveling saddle which moves parallel to the said axis, a varnish reservoir mounted on a standard carried by the said saddle, a bearing blockpivoted on the said standard and capable of swinging in a plane at right angles to the said axis, a nozzle carried bythe said bearing block and pressed thereby with a constant pressure against the periphery of the .rollershaped body, and a flexible tube connecting the said nozzle to the varnish reservoir.

In testimony whereof I have signed my name to this specification in the presence of I subscribing witnesses.-

EDUARD MERTENS.
